SPECIFICATION gtbrming part of Letters Patent No. 742,444,, dated October 27,1903. Application filed September 26,1902. Serial No. 124,912. (No model.)

To all? whom it may concern/.-

Be it known that 1, JOHN KEATS, a subject of the King of Great Britain, and a residentof Bagnall, in the county of Stafford, England, have invented certain new and useful Improvements in Machines for Preparing the Solesof Boots or Shoes, of which the follow ing is a specification.

The present invention'has reference to machines for preparing a marginal or stitching rib on the soles of boots and shoes a little distance from the edge for the attachment of the upper.

In common with other machines of the same class the machine which forms the subject of this invention is furnished with upper and lower pressing-tools and with a horizontal thrust-bar or abutment against which the edge ofthe sole bears during the operation of rib-forming, 0r fulling, as it is technically termed. These tools which perform the fulling. operation are according to this invention so arranged and driven that they act more efficiently on the work, are more easily manipulated than heretofore, and are also capable of easy andaccurate adjustment-to suit any thickness of leather and stitching-rib to be formed.

IntheaccompanyingdrawingsIhave shown a machine constructed according to the present invention.

Figure 1 is a front view. Fig. 2is a side elevation. Figs. 3 and 4 are front and side views of a detail detached'-viz., the device for operating the horizontal abutment. Figs. 5, 6, and 7 are top plan, edge View, and under plan of another detached detail-viz., the abutment itself. Fig. 8 shows in plan view an adjustable holder to which the thrustbar or abutment is pivoted. Figs. 9 and 10 show, detached, a construction of spindle for the upper fulling-tool, by which longitudinal adjustment is effected. Fig. 11 shows an alternative method of mounting and driving the upper falling-tool; and Figs. 12, 13, and 14 show the adjustable upper fulling-tool, the lower pressing-tool or support, and the thrustbar or abutment in their several positions for forming a marginal stitching-rib on the sole.

The machine comprises a framing a, wherein is mounted transversely a hollow driving shaft or sleeve b.. On the end of this sleeve 1) is loosely mounted a pulley c, constantly driven by any convenient source of power, and through the sleeve is passed a spindle d, the end of which projects beyond the pulley and carries a plate or disk e, with antifriction-wheelsfbearing against the face of the pulley c aforesaid. Fast on the sleeve 1) inside the pulley c is mounted a friction disk or plate g in such a way that when the spindle is pulled endwise the plate 6, bearing the friction-wheels f, thrusts the pulley 0 against the friction-disk g and causes the rotation of the sleeve Z) by the said pulley. The endwise movement of the spindle dis effected by the turning of the handle h, the boss of which forms a nut fitting the screwed end L of the spindle. The nut is prevented from endwise movement by a retaining-collarj, fixed to the framing a. The movement of the handle it pulls the spindle d endwise in the direction desired.

Upon the driving-sleeve b is mounted a toothed wheelkfor driving a train of gearingl art, through which are operated the upper falling-tool m and the horizontal thrust-bar or abutment 17 in the manner to be hereinafter described. The sleeve also carries a worm n, which engages a worm-wheel 0 on the horizontal shaft 19, which drives, through miter-wheels q r,the lower fulling-tool or support. The latter, 5, it may here be mentioned, is mounted'on a vertical spindle t, passing through the miter-wheel g, which is contained in a bearing situated in a casing u. on the main framing a and has a fixed position vertically therein. This spindle t has a free endwise movement through the wheel q, but is keyed thereto by a feather. An endwise adjustment of the spindle t is effected by means of an externally-threaded sleeve '0,

screwed into the bottom of the casing in line with the spindle t and provided with a winged locking-nut. The spindle t at its lower end is turned down, so as to fit loosely in the sleeve o, and is fitted with a retaining-nut to prevent its endwise movement in the sleeve.

The sleeve 4) is formed with a hand-wheel, by means of which an accurate upward or downward adjustment may be given to the lower fulling-tool or support 3.

The spindle of the upper fulling-tool cc (designated as a whole by the letter w) is composed of two parts 1 and 2, fitted together telescopically and connected by means of a nut y, which provides for longitudinal adjustment of the spindle, and consequently of the upper fulling-tool, to the surface of the leather. These parts engage together inside the nut in such a way that though longitudinal adjustment is permitted rotary connection is established and maintained. This arrangement is illustrated at Figs. 9 and 10. The part 1 extends down nearly to the fulling-tool 0c and is bored out to receive the part 2 of the spindle. At about the middle of its length the part 1 is threaded externally to receive the adjusting-nut y. The part 2 of the spindle is fitted with a transverse key 3, which is adapted to engage with the slot 40f the part 1, so that rotation imparted to the part 1 is communicated to the part 2. The two parts are held together by means of the nut g, which is rotatably secured to the part 2 by means of the collar 5 inserted therein and fixed by a small screw and screws onto the threaded portion of the part 1 more or less, according to the degree of longitudinal adjustment required.

The upper fulling-tool spindle is mounted ina swinging frame 6, which is pivoted to the top of the machine-frame abya horizontal shaft7, workingin bearings in said frame. The said spindle is provided with a wormwheel 8, engaging with a worm 9 on said shaft 7, which is driven through the main train of gearing is Z m. The upper fulling-tool may be carried on the end of the spindle itself or, if preferred for any special purpose, it may be mounted on a separate spindle 11, carriedon the same swinging frame as the fullerspindleand driven bythelatter through suit able gearing 12 13. (See Fig. 11.) The swinging frame 6 and the driving-spindle w occupy normally an inclined position. The said frame has applied to it a spring 14,which tends to thrust it and the spindle away from the perpendicular. To force the tool up to its work against the pressure of the spring, there is applied to the frame a screw 15, worked by a hand-wheel 16, which serves to adjust the spindle at various inclinations.

The horizontal thrustbar or abutment against which the work is pressed during the formation of the rib consists of a plate 17, arranged near the point where the upper and lower fulling-tools meet. This plate 17 is .pivoted at 24 (see Figs. 2, 5, 7, and 8) in a slide 18, adjustable in the direction of its length by means of ascrew z. The said plate 17 has a laterally-oscillating or to-and-fro movement on the pivot 24, communicated to it by a pin 19, secured, by means of a clamp 20, (see Figs. 3and 4,) toasliding bar21,which is moved endwise in its bearings by means of a cam-wheel 22, attached to and rotated by the wheel Z of the main train of gearin The position of the pin 19 on its supportingbar 21 is adjustable by shifting the clamp 20 endwise on said bar, so that the horizontal plate may be set laterally in either direction, as desired. 7

In operation the sole to be worked upon (indicated by 23 in Fig. 12) is inserted between the upper and lower fulling tools in such a way that its edge (preferably slit) bears up against the thrust-bar or abutment. The machine is then started by means of the friction-clutch above described, and the upper fulling-tool is caused to bear against the surface of the sole by means of the screw and hand-wheel.

Fig. 13 is an illustration of how by feeding the upper fnlling-tool downward by means of the nut y it has forced its way down into the leather and thrust the portion of the leather in front of it to one side or behind the bent-up edge of the split sole.

Fig. 14 shows the completely-formed rib, the result of feeding the fulling-tool downward and at the same time moving it laterally in a horizontal plane toward the thrustbar or abutment 17. The rotation of the fulling-tools gradually feeds the sole along until the marginal rib is complete.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a spindle for a sole-fulling-machine tool, the combination of two parts one of which is fitted to slide lengthwise within the other which has an external screw-thread, an adjusting-nut fitted to said screw-thread and provided with an internal collar, and a key on one of said parts engaging with a longitudinal slot in the other and confined by said collar to form a rotary connection between the two parts of the spindle while permitting their longitudinal adjustment.

2. The combination in a sole-falling machine, of an abutment for the edge of the solo, a supporting-slide for said abutment, a pivotal connection between said abutment and slide, a bar arranged transversely to said slide, means for reciprocating said bar longitudinallyand adjustable means for imparting an oscillating motion to the pivoted abutment from the reciprocating bar.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN KEATS.
